Fence posts are vertical structures used to support a fence. They are typically made from materials like wood, metal, or vinyl and are installed at regular intervals along the fence line. The posts provide stability and help keep the fence upright, ensuring it serves its purpose effectively. The height and spacing of fence posts can vary depending on the type of fence being built, such as a wooden fence or a chain-link fence. Proper installation is crucial, as securely anchored posts can withstand weather conditions and prevent the fence from leaning or collapsing over time.
